TACK-FASTENED BUTTON.

Specification of Letters Patent.

Patented July 22, 1913.

Application filed April 28, 1913. Serial No. 764,224.

To all whom it may concern:

Be it known that I, FREDERICK E. STAN- LEY, a citizen of the UnitedStates, residing at Waterbury, in the county of New'Haven and State ofConnecticut, have invented a 'certain new and useful Improvement inTack-Fastened Buttons, of which the following is a full, clear, andexact description.

In the manufacture of that class of metal buttons where a. hubbed backhas a shell or face applied to it, it sometimes happens t at the shellor face is applied to the back so loosely or inaccurately as to turnthereon. This is an objectionable feature inthe trade, and while suchloose buttons are not readily discovered and discarded in the factory,they are found by the consumer, and are a source of trouble both to theconsumer and the manufacturer. The difliculty may arise in any lot ofbuttons running through the assembling machine, and may be due to slightvariation in the back, or in the temper or thickness or springiness ofthe metal of the face, causing such face to spring away from the back.It requires considerable time and experimentation in cutting and tryingon the part of the tool-maker, to provide machines to preventthismishap, and even then his efforts are not always entirely successful.

The present invention has for its object the production of a button freefromv the stated defect, and practically insuring the tight closing ofthe shell or face on the back,

in such way as to prevent relative turning of the parts, whilepreserving the circular rim and appearance of the button.

The invention consists of a button, in which the back has a series offacets or flat or plane faces, terminating in a circular rim, and towhich the shell or face is applied in such way that its flange willengage the facets, which by their interposed angularity prevent therelative turning -of the shell or face on the back, without altering thecircular rim'formation.

In the accompanying drawings, illustrating the invention, in theseveralfigures of which like parts are .similarly designated, Figure 1 is a topplan view; Fig. 2 is an inverted plan view, and Fig. 3 is an edge viewof the shell or face. Fig. 4 is a top plan View; Fig.5 is an invertedplan view; and Fig. ii is aside elevation of the faceted back. Fig. 7 isa top plan view; Fig. 8 is an inverted plan view, and Fig. 9 is alongitudinal section of a button made up of the illustrated shell or capand back.

The shell or face 1, may be of any usual material and form, and has theusual flange 2, by which it is closed down upon the back 3. This backalso may be of usual material and form, excepting that next to itscircular rim 4: it is provided with a continuous series of facets 5which run out to nothing in the rim 4 and the body of the back next toand adjoining the hub 6.

When the shell or face is closed down over i the faceted back, by anyusual machinery, its flange 2 hugs the facets 5, or their meetingangles, closely enough to prevent the shell or face from turnihg uponthe back.

By the construction described, not only is the objection of loose shellsor faces obviated, but the manufacturer is enabled to use a shell orface ofthinner metal than formerly, and of harder temper, and secure auniform frictional contact of the closed members. It does not require somuch time for the closing tools to be prepared, because the grip of theshell to the back may be made quite readily with closing tools of pro ersize and almost any shape. The retentlon of the circular-rim form of thebutton is of importance also.

What I claim is 1. A tack-fastened button, having a faceted back, and acircular shell or'face closed down upon and engaging the faceted backand thereby held from independent turning.

2. A tack-fastened button, having a faceted back, the facets running outto nothing in a circular rim, and a shell or face closed down upon theback and held from turning 3. A tack-fastened button, having a hubbedback, a circular rim, and facets intervening between the rim and hub,and a flanged shell or face having its flange closed down upon thefaceted back and engaging its facets.

In testimony whereof I have hereunto set my hand this 26th day of AprilA. 'D. 1913.
